Hydrogen Production by Coal Gasification Coupled with in Situ CO2 Capture
Abstract: CO2 adsorption enhanced gasification process is a prospective technology to be used in hydrogen production with nearly zero CO2 emission. In this paper, a gasification kinetics steady state model is developed based on the chemical kinetics mechanism with the condition of fluidization. It is used to predict the parameters of gas phase and solid phase for a continuous flow reactor with steady state. The variation of components distribution with gasification temperature and pressure are determined, from which the optimal operation parameters of gasifier can be obtained.
